YPXFR(8)                  BSD System Manager's Manual                 YPXFR(8)

NAME
     ypxfr -- get a YP map from YP server

SYNOPSIS
     ypxfr [-bcf] [-d domain] [-h host] [-s domain] [-C tid prog ipadd port]
           mapname

DESCRIPTION
     ypxfr is the utiliy in YP that transfers maps to the local host.

     Since the YP master transfers a map when it has changed, an YP slave
     should check for missed maps regulary. This can be done via an entry in
     crontab(5).  The scripts ypxfr1perhour, ypxfr2perday and ypxfr1perday
     could be used for that.

     The options are as follows:

     -b      Preserve the entry in the database informing a YP server to use
             DNS to get information about unknown hosts. This option will only
             have effect on the two maps hosts.byname and hosts.byaddr.

     -c      Don't send a "Clear current map" to local ypserv process. Useful
             if ypserv isn't running localy to avoid timeout message.

     -f      Force map transfer, even if version of master is older than local
             copy.

     -d domain
             Don't use default domain, use the specifiyed domain.

     -h host
             Get map from host insteed of the maps master host.

     -s domain
             Specify a source domain other than the target domain.

     -C tid prog ipadd port
             This option is only used by ypserv. This is to open communication
             with an yppush on another host.
